1/4 cup soy sauce
3 tablespoons toasted sesame oil
1/4 teaspoon crushed red pepper flakes
1 1/2 teaspoons minced garlic
1 1/2 pounds Brussels sprouts,trimmed and halved
4-5 tablespoons peanut oil

Combine soy sauce, sesame oil, red pepper, garlic and 3 tablespoons water in a large bowl. Blanch the Brussels sprouts in boiling water until partially tender,3-4 minutes. Drain well. Heat a wok or large cast-iron skillet over high heat until hot,2-4 minutes. Add a small amount of the peanut oil,swirl the pan to coat the surface and add about a third of the sprouts. Stir-fry until bright green and crisp-tender. Drain on paper towels. Stir fry the remaining sprouts similarly in batches. Add stir-fried sprouts to soy sauce mixture and toss well. Serve immediately or allow the Brussels sprouts to marinate an hour before serving.
